Together with a study of object complements, a succinct description of the Malay classifier construction is given. Object complementation is studied in a generative-transformational framework. For sentence object complements, four types of surface structure are proposed, but it is claimed that two types of deep structure trees underlie the sentence object complement construction. Two informants, one from Selangor State and the other from Malacca State, were used for the study. (Author/KM)
